This is a spot where we can consider firing once or thrice. Don't think a double barrel strategy works here because whatever he called the Flop with is not folding the turn too much. Those hands are mostly pair+draw type of hands like JT QJ KT J9s and those hands will only fold to a third barrel.

I think the Flop bet is fine to fold out undercards and underpairs like 22. And based on his stats on how often he folds vs F and T cbets I think the answer is clear - we should only fire once.
